There are so many variables for appropriate door hardware, it makes sense that there are still specialized companies to provide and design door hardware. Of course there are cases as integrators (which I am) where there is an existing facility and we are asked to secure that one particular door that stumps us. My current specialty door is a commercial sliding glass door (See picture below). The door operated as the previous owner dictated via PIR sensor, automatically. My recommendation to the new facility owner was to allow the ACS to override the PIR control point to limit access to authorized personnel and keep the added benefit of creating auto unlock schedules for normal operation when desired. The new owner has decided that this is not secure enough and wants a hard locking solution. The only possible thing I have been able to come up with so far is mag locks on Z brackets and have 2 stage override so that the door did not activate with a motor pulling while the mag is holding (messy, messy). I am hoping that someone out there has come across this issue and come up with a more elegant solution. Any advise and knowledge is welcomed!!
